Abstract: A hand-held portable video camera and radiation monitoring apparatus which can be deployed by a single operator in the field is disclosed. The apparatus uses a compact, extendable probe which provides real time visual monitoring via a video camera along with real time radiation detection and identification of isotopes. The apparatus includes software which identifies and reports to the operator via a speech synthesizer the identification of specific isotopes.

Abstract: A mobile robotic system that conducts radiological surveys to map alpha, beta, and gamma radiation on surfaces in relatively level open areas or areas containing obstacles such as stored containers or hallways, equipment, walls and support columns. The invention incorporates improved radiation monitoring methods using multiple scintillation detectors, the use of laser scanners for maneuvering in open areas, ultrasound pulse generators and receptors for collision avoidance in limited space areas or hallways, methods to trigger visible alarms when radiation is detected, and methods to transmit location data for real-time reporting and mapping of radiation locations on computer monitors at a host station. A multitude of high performance scintillation detectors detect radiation while the on-board system controls the direction and speed of the robot due to pre-programmed paths.
